#x= {2, a}#

Explanation:

To solve this equate each term on the left side of the equation to #0# and solve for #x#:

Solution 1)

#x - 2 = 0#

#x - 2 + color(red)(2) = 0 + color(red)(2)#

#x - 0 = 2#

#x = 2#

Solution 1)

#x - a = 0#

#x - a + color(red)(a) = 0 + color(red)(a)#

#x - 0 = a#

#x = a#
